The hardware that can turn real instruments, from guitars to drums to keyboards, into Rock Band 3 controllers arrived a little later than some rhythm game fans were hoping for. And Mad Catz is sorry about that.

The Wii and PlayStation 3 versions of the Rock Band 3 MIDI Pro Adapter are now available for your rocking pleasure, with the Xbox 360 version coming soon. It was real and working at this weekend's Consumer Electronics Show, a device that Mad Catz's Alex Verrey and crew demonstrated using the Fender Stratocaster and a Roland MIDI keyboard.

If you're in the market for either a Rock Band 3 MIDI Pro Adapter and/or an apology from Mad Catz, watch the video below.
